Thank you for downloading Signa. We hope you enjoy using this plugin and that it inspires new ideas.

Introduction

Signa is an instrument plugin designed as an explorative device — a way to uncover new sonic worlds. Built from a library of original synthesiser recordings, every sound in Signa began with a single question: If distant planets sent us signals, what would it sound like if it was a pure tone or texture?

That idea shaped not only the sounds themselves, but the instrument's entire design philosophy. The controls may feel alien at first — abstract, perhaps even untranslatable — yet they remain intuitive once you begin to listen and respond. Signa was created to make discovery immediate: lush, experimental pads are just a few clicks away.

At its core, Signa is built on three layers: two tonal and one textural. Blended together, they form a singular, evolving voice. Despite its otherworldly nature, simplicity remains central to the experience. You may often wonder, What does this control do? That curiosity is part of the design, but you can find the answers here, in this manual.

We hope Signa inspires you to listen differently — to explore, to experiment, and to discover sounds that feel like messages from the stars.

Installation

Once you've downloaded the file, extract the ZIP and run the installer. By default, the plugin is installed into:

Once installed, open your preferred DAW. Signa is a VST3 and AU plugin, so you'll need to ensure your DAW is set-up correctly to find and load the plugin. The above directories are where most DAWs expect these files to be — otherwise some hosts can't find a plugin on the machine. E.g. this is the case for FL Studio or Cubase with VST3 files.

Using Signa

Signa is an instrument plugin, so to get started, load Signa onto an instrument/MIDI track inside your DAW.

When you first load the plugin, it will load the default preset. Play a note on your keyboard to hear Signa. Click the folder icon top right of the plugin to browse some of the factory presets.

When you're comfortable, let's walk through the main controls.

1 — Signal Selection

The 3 pillars on the UI represent the 3 signals from distant planets. The first layer, furthest to the left, is what we will concentrate on. The controls are copied to the other layers, except control 8 which is described below.

The 2 pillars to the left are tonal signals, represented with a circle on the UI — whereas the signal furthest to the right is texture, represented with a Square. Click and drag on these pillars to load a different signal. There are 100 tonal signals and 100 texture signals. There are a million different combinations you can make with just these 3 signals.

You can also hover on the left/right side of the pillars, to see a highlighted segment — this moves the signal by 1 step increments up (right) or down (left). The current amplitude of the currently loaded signal is represented with an animated column furthest to the left of each pillar.

2 — Octave

The 2 tonal signals have octave controls, represented with these 5 nodes. The middle button is the default pitch, whereas the top 2 nodes increase the octave, and the bottom 2 decrease the octave of the signal.

3 — Volume

Increase or decrease the volume of the signal.

4 — Volume Modulation

This increases the amount of volume modulation to the signal. At 0, there is no modulation.

5 — Modulation Flux

These small circle controls change both the rate and depth of the modulation, linked to the fader it is adjacent to. At lower values, the modulation will be deeper, slower and more pronounced. As the value increases, the modulation will become quicker and more unstable.

6 — Pan Modulation

This increases the amount of stereo panning modulation to the signal. At 0, there is no modulation. There is also a mod flux control to the left.

7 — Flutter

This adds tape inspired pitch flutter to the tonal signals. There are 4 settings, each increasing the flutter amount and depth as the value increases.

8 — Tone

Unique to the texture layer, this is a bandpass filter for tailoring the noise to a frequency of your choice.

Crush

Crush introduces bit crushing to the layers — perfect for adding noise and digital texture.

Rescan

Rescan immediately randomises the chosen signals, giving you 3 different layers.

Resize Plugin Window

If you wish to resize the plugin window, just drag and drop the bottom right corner of the plugin to set a desired window size.
